Epic of Gilgamesh

Story:

Tludia abruptly left the Order before she could complete her training to become a Knight because she broke too many weapons and ate too much. But it doesn't mean she should do nothing when she sees an elderly guy being approached by a group of robbers. Fortunately for her, the elderly man did not require saving because she arrived a split second too late. Tludia has to be saved. Tludia, who is much older than he appears to be, brings back a long-forgotten memory in him, and he decides to thank her by discovering a treatment for her illness (with promises of food, of course).
